ELO Mode Deck

I begin playing in ELO Mode recently, and i've been with some difficulties to make my deck. I've been using almost Fang Pi Clang cards in my deck, but i've never reached a good performance with them. In normal mode, i use them a lot because of their high Damage points with their Bonus, but in ELO mode it seems like what matthers the most are the Attack points. Am i right ?
